ploting between infected pepole and reproduction number

i want to plot between

dx(3,:) = sigma * x(2) - (gamma+d+m)* x(3);

R0 = (sigma*beta*A)*(d*(1-u)+alfa)/d*(d+alfa)*(d+sigma)*(d+m+gamma);

dx is infected class .

i want to plot between infected people and reproduction number

i want to plotting between

this my trail work

I = (d+sigma)*(R0-1) / eta*(d+alfa)*(d+sigma)+beta*(d+alfa+sigma);

R0 = 0:5;

A=100;d=0.1;eta=0.9;gamma=0.025;alfa=0.4;sigma=0.8;m=2;u=0.5;beta = 0.01;I=0;

plot (R0,I,'r')

my result is in figure1 but i want to point out like this image

can you help me or please guid me

R0 = 0:0.5:5;
A=100;
d=0.1;
eta=0.9;
gamma=0.025;
alfa=0.4;
sigma=1.3;
m=2;
u=0.5;
beta=0.01;
logic_data=R0>=1; 
I = logic_data.*((d+sigma)*(R0-1) / eta*(d+alfa)*(d+sigma)+beta*(d+alfa+sigma));
plot (R0,I,'r')
ylim([-1 5]);
grid on; 

#Please change parameters the typical values accordingly (Sigma).
